Get weight reduced somehow — cook using this (3,5)
I believe the answer is:
egg white
'cook using this' is the definition.
The definition suggests a singular noun which matches the answer.
'get weight reduced somehow' is the wordplay.
'reduced' means to remove the last letter.
'somehow' indicates anagramming the letters.
'get'+'weight'='getweight'
'getweight' with its final letter taken away is 'getweigh'.
'getweigh' with letters rearranged gives 'EGG-WHITE'.
Can you help me to learn more?
(Other definitions for egg white that I've seen before include "Meringue ingredient" , "Cake ingredient" , "Albumen, not the yolk" , "Albumen, transparent ovum content" .)
